Dia mengepam tayar.

Yes. Dia can mean either he or she. Malay third-person pronouns usually do not show gender, so you understand it from context.

For example, Dia mengepam tayar could mean:

• He is pumping a tire
• She is pumping a tire

Pam is the root word, meaning pump. In standard Malay, active verbs often take the prefix meN-.

Because pam is a one-syllable root, it usually becomes mengepam with menge-.

So:

• pam = the root
• mengepam = to pump / is pumping

In casual speech, people may sometimes say Dia pam tayar, but Dia mengepam tayar is the more standard full form.

This is a common pattern with one-syllable root words in Malay.

Examples:

• pam → mengepam
• cat → mengecat

So menge- is often used when the base word has only one syllable. That is why it is mengepam, not mempam.

It usually means pumping air into a tire, in other words inflating a tire.

So even though the literal verb is pump, in context it often means something like:

• inflate a tire
• pump up a tire

Malay does not use articles the way English does. There is no direct equivalent that must appear before every noun.

So tayar can mean:

• a tire
• the tire
• sometimes even tires, depending on context

If you need to be more specific, Malay usually does that in other ways, such as with context, numbers, or words like itu.

For example:

• tayar itu = that tire / the tire
• satu tayar = one tire

By itself, tayar can be either singular or plural. Malay nouns usually do not change form to show plural.

So Dia mengepam tayar could refer to:

• a tire
• the tire
• tires, if the context makes that clear

If the speaker wants to make the number clear, they can add a number:

• Dia mengepam dua tayar = He/She is pumping two tires

Malay verbs do not change form for tense the way English verbs do.

So mengepam does not itself mean specifically is pumping, pumped, or will pump. The time is usually understood from context or from time words.

Depending on context, Dia mengepam tayar could mean:

• He/She pumps tires
• He/She is pumping a tire
• He/She pumped a tire

In beginner examples, it is often translated as a present action, but context is what really decides it.

You can add sedang before the verb.

• Dia sedang mengepam tayar = He/She is pumping a tire right now

Sedang makes the ongoing action more explicit, like the English be + -ing form.

Yes, in this sentence it is very similar.

The order is:

• Dia = subject
• mengepam = verb
• tayar = object

So it follows a Subject–Verb–Object pattern:

• Dia mengepam tayar
• He/She pumps a tire

That makes this sentence quite straightforward for English speakers.

A simple rough guide is:

• Dia → dee-ah
• mengepam → muh-ngeh-pam
  The ng is like the sound in sing
• tayar → tah-yar

Malay pronunciation is usually fairly regular, and each written vowel is normally pronounced.

It means the same thing. The difference is only in English spelling:

• American English: tire
• British English: tyre

Malay tayar refers to that same object.

Not normally. Dia mengepam tayar is an active sentence, and dia is the doer of the action.

So the structure means:

• He/She is pumping the tire

If you wanted a passive idea like The tire is being pumped, Malay would normally use a different structure, such as a passive form with di-:

• Tayar itu dipam = The tire is being pumped / The tire was pumped

Sometimes in conversation, yes, if the subject is already obvious from context. Malay often drops words that are understood.

So in real speech, someone might simply say:

• Mengepam tayar
• Pam tayar

But as a full clear sentence, especially for learners, Dia mengepam tayar is a good standard form.
